Answer: yes
Step-by-step explanation:
If you graph the function on desmos or a graphing calculator, you will see that it passes the vertical line test.
The graph is a function when no one x value has two y values, this is why we use the vertical line text to see if the graph is a function.
ANSWER
The possible rational roots are:

EXPLANATION
According to the rational root theorem, the possible rational roots of the polynomial,
are all the possible factors of the constant term divided by all the possible factors of the coefficient of the highest degree of the polynomial.
Therefore we examine the numerator and denominator of the options provided to see if they are factors of 10 and 4 respectively.
For
, we can see that 1 is a factor of 10 and 2 is a factor of 4, hence it is a possible rational root.
The same thing applies to
also.
As for
, 2 is a factor of 10 but 5 is not a factor of 2, hence it is not a possible rational root.
Maybe u add them up does it say area if so its multiply from it says a diff word I forgot it's subtract
